7 IMPROVEMENT iN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 59,629, dated ovember13, 1866.

To all whom it may concern f Be it known that I, A. L. MUNSQN, of the(both ends being made alike) so that in loading the chambers in thecylinder by inserting the cartridge in one end thereof thecartridgeshell is ejected from the other end.

Figure 1 represents a fire-arm, a portion of which is shown in section,illustrating my improvement. Fig. 2 is a cross-section of the same,taken on the line or m, Fig. 1. Fig. 3 is a side view of a cylinderembracing my improvement in another form.' F-i gfet is an end' view ofthe same.

Fig. 5 is asectional view of a cylinder, showing another modification.

Fig. 6 is an end viewof Fig. 5. 1

Similar letters of reference indicate corresponding parts. '3 I will nowdescribe what I consider the best means of carrying out my invention. 7

A represents the frame of a fire-arm. B is the barrel; B, a projectionfrom the barrel which supports one end of the center-pin d. e is aratchet wheel or disk, detached from the cylinder 0, and held in placeon the pin m by means of a plate, 0, or its equivalent, as shown in Fig.2. i is a small pin projecting from the ratchetwheel or disk 0, whichfits into a hole in either end of the cylinder 0, locking the cylinderto the ratchet-wheel, so that they will revolve together. r

The center-pin d is constructed in two parts, and connected together bymeans of a screwthread on the end of the connecting rod or neck, whichis made of less diameter than the pin 61, forming shoulders on the pin,which limit its movement by coming in contact with the projection n onthe cylinder 0.

' Figs. 3 and 4 and 5 and 6 represent cylinders having aratchetarrangement oneach end. In that shown in Figs. 3 and 4 theratchetprojection, which is of the ordinary and wellknown form, could beusedas a center-pin for the cylinder 0 to revolve on. In Figs 5 and 6the ratchet arrangement is made of projecting pins placed in a recess ineach end of the cylinder, flush with its face, and corresponding withthe number of chambers.' This arrangement of the ratchet renders myimprovement applicable to many varieties of fire-arms.

The operation of my improvement, applied A outward, as shown in Fig. 5,(the cartridges thus acting as a cartridge-shell ejector.) The fcylinder is then reversed and placed back into the frame. The movablecenter-pin d, coming in contact with the pin m, is forced backward untilits shoulders come in contact with the projection a on the cylinder 0.At the same time the cylinder 0 is turned until the pint enters the holei. The barrel is then moved into position, and the arm is ready for use.

Having thus described the nature, construction, and operation of myinvention, what I claim, and desire to secure by Letters Patent,is-

1. The reversible cylinder 0, in combination with the detached ratchet eand plate (or collar) 0, or its equivalent, substantially as and for thepurpose described.

2. The center-pin d, in connection with the pin m, operatingsubstantially as and for the purpose described.

In testimony whereof I hereunto sign my name this 10th day of May, 1866.,1
